Problem with HIGHMEM implementation for 32 bit mips-el port

[<Rishabh@soc-soft.com>]

Hi all,

 

I am working on MIPS32 port of linux (kernel version 2.4.18) for R4000 processor. While compilation was fine but the kernel boot up panics in “init”.

 

I have 128MB RAM on the system where 64MB is located at 0x00000000 physical address and the other 64MB is located at 0x20000000.

 

Also how is the address map for mips defined (highmem)?

 

Regards,
